Sir I cannot understand the last line of the answer of my previous question that you have answered and the line was A is just a member of set C, it is not a subset of C.

Initially A is a set, but when you see A belongs to B that means A now can be seen as 2 things, one as a set and second as a member of a set B. So when B becomes subset of C this means every member of B becomes the member of C. Now since A is a member of B, so it also becomes a member of C.

I am confused in a question from SETS AND RELATIONS P(A:B)={X:X∈P(A),B⊂X} In the given statement, does P(A:B) mean power set of ratio of set A and B? Please correct me if I am going wrong because I am not sure about it.
